38. Measurements are made of the intensity distribution within the central bright fringe in a Young's interference pattern (see Fig. 36.5). At a particular value of y, it is found that I/ - 0.810 when 600-nm light is used. What wavelength of light should be used to reduce the relative intensity at the same location to 64.0% of the maximum intensity?
Review I Consta The two most prominent wavelengths in the light emitted by a hydrogen discharge lamp are 656 nm (red) and 486 nm (blue). Light from a hydrogen lamp illuminates a diffraction grating with 550 Part A lines/mm , and the light is observed on a screen 1.6 m behind the grating.
